Abstract: The study examines whether the form of maltreatment experienced by the child moderates the effects of a parent training program (PTP) on the probability that the child’s case will be closed and that the child will be the subject of a new founded report to child protective services (CPS). This study involved 736 children on whom the Montreal CPS agency had an active file between 2007 and 2015. The experimental group was composed of all children with a parent who participated in the PTP Incredible Years (n=368). A control group was matched with the experimental group based on a propensity score. Cox regression revealed that once parents have participated in the PTP, the probability that their children’s cases will be closed increases more for children being followed because of neglect than for those being followed because of emotional maltreatment. Participating in the PTP has no effect on the recurrence of reported maltreatment, regardless of what form of maltreatment the child has been subjected to. Results show that a parent’s participating in a PTP increases the probability that his or her child’s CPS case will be closed and hence reduces the length of time that the child must receive protective services.
